For other meanings of the term, see backfire (disambiguation). A back-fire or backfire is combustion or an explosion produced by a running internal combustion engine that occurs in the air intake or exhaust system rather than inside the combustion chamber.
The cost of repair will obviously depend on the problem. For example, if the misfire is caused by a bad on-plug ignition coil, which is quite common on many newer cars, the repair might involve replacing a bad coil and all the spark plugs. This could cost $300-$400 for a 4-cylinder engine or $450-$700 for a V6.
